摘　　要：采用微絮凝超滤工艺对微污染水中氨氮的去除进行了试验研究。结果表明，该工艺能有效地去除水中的氨氮，验证了有机物含量对氨氮去除的影响，同时得出了采用铝盐和铁盐混凝剂的最佳投加量为2．5mg／L，最佳pH值为5．5～6．0。The micro-flocculation and ultrafiltration process used for removal of ammonia nitrogen from weakly polluted source water was examined. The results indicate that this technique can effectively remove the ammonia nitrogen from weakly polluted source water, and the influence of the organic content on the ammonia nitrogen removal is validated. Simultaneously, it is concluded that the best dosage of aluminum salt and iron salt coagulant is 25mg/L, and the optimal pH value is 5.5 - 6.0.
